CARBURETER.

Application filed May 28, 1912.

To all whom t may concern.'

Be it known that I, ADAM R. HENDRIX, a citizen of the United States,residing at Chicago, in the county of Cook and State of linois, haveinvented certain new and useful Improvements in Garbureters forInternal-Combustion Engines or the like, of which the following is adescription. y

My invention relates to that class of devices known as carbureters ormixers for iinely dividing a fluid hydro-carbon and discharging the sameinto, and thoroughly mixing the same with, a certain volume of air toform a combustible explosive mixture.

The object of my invention is to provide a device of the kind describedwhich can be operated under substantially any conditions of weather ortemperature, suitable for use with the more non-volatile liquidhydrocarbon and with' a certainty of the accurate and reliable operationof the device and the production of a uniform mixture.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described and moreparticularly pointed out in the claims.

In the accompanying drawings wherein like or similar referencecharacters indicate like or corresponding parts;

Figure 1 is a central vertical section of my device.

Fig. Q is a detail elevation of the controllingV mechanism of my device.

Fig. 3 is a fragmentary section taken substantially on line 3-3 of Fig.2.

Fig. 4 is a section through the mixing tube of my device takensubstantially on line 4--1 of Fig. 1.

In the form'shown in the drawings l is a tubular casing preferably ofsubstantially uniform size its entire length with a fuel receptacle 2rigidly secured on one side with a neck or stem 3. A port l extends fromthe interior of the receptacle 2 into the casing 1. The end 5 of theport adjacent the casing is conical, and a conical valve 6 is positionedin the casing and arranged to close the port. A stem 7 extends throughthe receptacle 2 with a hand wheel 8 or other convenient means upon itsend for conveniently adjusting the position of the valve. A gland 9 orother suitable means is also provided to prevent the escape of fluidfrom the receptacle 2 adjacent the hand wheel.

the receptacle reaches the point of overiiow the height of the fuel willbe accurately maintained as long as a suiiicient amount of liquid issupplied. The overflow may of course, be connected to the main fuelsupply tank or other convenient point that will per` mit the fluid toescape by gravity. A small vent pipe 12 is also provided in the top ofthe receptacle to prevent air imprisoned within the receptacle tointerfere with the regular operation of the device.

rlhe casing 1 is preferably circular in section and provided with anydesired number of butteriy valves or dampers 11k-15 adapted te controlthe flow of air through. the casing. The valve 1-1 is positionedsubstantially opposite the port l and the valve 15 is positionedslightly nearer to the discharge end of the casing. The shafts or axisof the valves extend `through the wall of the casing at one side and areeach provided with a; crank, or handle 16 and 17 respectively so thatthe position of the valves in the casing may be accurately determinedand adjusted by the position of the respective cranks.

In the preferred construction a link 18 connects the cranks 16 and 17 sothat a movement of one will produce a corresponding movement of theother thereby providing for the simultaneous adjustment of the valves.Any suitable means may be provided for locking the valves in position.In the form shown a yoke or segment 19 is loosely mounted upon the shaftof the valve 14 between the arm 16 and the casing 1 with a suitablyformed slot 20 in its periphery. The arm 16 preferably projects beyondthe [ink 18 as shownand is provided near its extremity with a bolt orother convenient means extending into the slot 20 so that when desiredthe arm may be rigidly secured to the segment in any desired position. Alink or rod 22 is pivotallyattached to the segment 19 and connected tothe governing mechanism of the motor or if desired may be carried to anyconvenient point for manually controlling the position of the segmentand thereby control the opening through the casing and the operation ofthe motor. 0b-

' The apertures viously if it is not desired to provide such automaticgoverning mechanism or to control the operation of the motor from adistanceJ the segment 19 may be rigidly secured to the casing 1 or ifdesired cast integrally therewith so that by securing the arm 16 to thesegment the valves will be rigidly held until further adjuster.

The casing 1 is preferably entirely open at one end as at 2e while theopposite end is provided with a perforated plate 25 and connected beyondthe plate 25 in any suitable manner as by the tube 26 to the cylinder orcombustion chamber of a motor or other point where the mixture is to beconsumed.

27 in the plate 25 are preferably angular as shown so that, in additionto operating as a strainer for preventing large pieces of material frombeing drawn into the cylinder' the plate 25 also serves as a mixer forfurther breakingup the larger globules of the liquid and more intimatelymixing them with the air. A cap or cover 28 is provided for the end 1 toprevent dust and other foreign material from entering the casing andthus finding a direct passage to the engine cylinder.

In operation the desired liquid fuel is pumped or otherwise suppliedthrough the pipe 10 to the receptacle 2 as soon as the receptacle isfull, that is, as soon as the fluid begins to escape at the overflow 11the hand wheel 8 may be operated to 'slightly open the valve 6 so thatfluid will flow through the port with its conical part 5 into the casing1 although under ordinary cir cumstances when the valve is sufficientlyopen for the proper operation of the device the fluid 4will be largelyheld by capillary action and will not flow to any considerable extentinto the casing. When the engine is started however, the reduction inair pressure in the tube or suction of the engine is sufficient to drawthe fluid rapidly through the conical space about the valve 6 therebydischarging the fuel into the casing in a fine spray. The largerglobules are projected against one side of the bi'itterfly valve 14 andthe remainder is carried down by the air and more or less distributedover the surface of the valve 15 and plate 25 so that the air rushingthrough the casing 1 is brought into intimate contact with the fluidupon the valves and operates to wipe the fluid from the valves andintimately inizi the sanie with the on rushing air. `The larger globulesof fluid which may be thrown from the valve 14 are caught upon the valve15 or the plate 25 and again broken up as it passes through the platethereby producing an extremely intimate and substantially permanentmikture. The position of the butterfly valves obviously controls theclear space through the easing and thereby the velocity of the 'airpassing through the casing, and, since the Q4 of the casing amount offuel entering the casing is largely controlledby the differenceinpressure or velocity of the air passing through the casing theposition of the butterfly valves aecurately controls the amount of fuelused 1n the engine and thus, within certain limits, the power developedby the engine. Y Y

While in the foregoing specification I have shown and described a verydesirable form of my invention, it is obvious that various parts may beconsiderably modified without departing from the spirit of my invention,I do not therefore wish to limit myself to the exact form orconstruction shown.
